未知的C＃类型 [英] Unknown C# type

问题描述

我有一个方法 exMethod 返回的值是这样的：

 返回新{名称=名字，姓氏=姓};
 

和我用这个code

 变种人= exMethod（）;
 

但在这一点上，我怎么能访问到它的领域？我试着以

  person.name
 

但引发的异常

 对象不包含名称的定义
 

解决方案

匿名类型不能在方法的边界通过，而不会失去它们的类型（它们将恢复到对象）。既然你可以不投它，你被卡住。

您必须创建一个类型暴露出的创作方法的外面。 （我不想提动态作为一个解决方案）

I've a method exMethod that return the value in this way:

return new {name = name, surname = surname};

and I use this code

var person = exMethod();

but at this point how can I access to its fields? I've tried with

person.name

but is thrown the exception

'object' does not contain a definition for 'name'

解决方案

Anonymous types can't be passed across the boundaries of a method without losing their type (they will revert to object). Since you can't cast it, you are stuck.

You have to create a type to expose that to the outside of the creating method. (I don't want to mention dynamic as a solution)
